IMPROVEMENT IN BATH-TUBS.

The Schedule referred to in these Letters Patent and making part of the same.

the' bath-tub 'with a circular projecting flange, surrounding the opening in the bottom of the tub, through which the waste water is discharged, said flange being provided with a female screw-thread, in which tightly tits a short brass pin". This brass plug has a screwthrcad cut on each end of the same. The upper thread enters the female screw of the circular flange as before stated, while the lower thread receives and retains the ordinary screw-coupling, by means of which the waste pipe is securely attached. p

My invention also consists in constructing the screwplug with an opening in its side, to which is firmly united the curved end of a pipe. The other end of this pipe is also curved, and firmly soldered around the ovcrtlow-opening in the upper sectionof the footboard ot'tho tub. A

Experience has fully attested the practical utility of this arrangement, and its vast advantages over all former arrangcmentsf By-constructing the pipe with suitably-curved ends, a secure, durable, and exceedingly neat connection is tin-med between the overflow-opening and the connecting-pipe beneath the tub, and the main section of the pipe runs in such close proximity to tho baseof the tub, that the room required for the successful operation of my improvement is not more than two orthree inches.

The advantages of my arrangement, as well as its clieapness, in comparison with the method now gcncrally used, will readily suggest themselvcs to any one skilled in the art to which my invention appertains.

The usual mode of czu'rying otithc overflow is to solder an elbow of two pieces into the tub, and secure the same toa lead pipe on the outside. This pipe is cithcr connected with the waste-pipe, or runs off as an independent pipe.

In all the methods now in use, in which the overflompipo is connected with the waste-pipe, it is inrpossible to break the connection without sawing on the waste-pipe In my invention all these complications are dispenscd with, and all these disadvantages avoided.

My construction of the pipe renders the use of the elbow entirely unnecessary.

I do notattach the overflow-pipeto the waste-pipe. but to a screw connecting-pipe, which can be readily attached to or detached from the tub.

I am aware that an attempt has been cssayed to accomplished the results attained by my invention, by securing a grooved foot-board to the ordinary tub. A

lnoments reflection will clearly show the entire impracticability of the proposed plan. and the vast superiority of my arrangement.

One objection alone that can he trnt-hfr'illy advanced is fatal to its success, and demonstrates its entire impracticabilityas well as the impossibility of its going into general use. i

The objection is this: In the plan alluded to, you cannot obtain a tight joint, and without which it is idle to think of its satisfactory working. The grooved board is secured to the foot-board of the tub. This grooved board must be constructed withafla-nge pass ing under the tub, so as to form a connection with the *aste-pipo. A tight joint cannot be formed by-any known means with either thewaste-pipc or overflowopeninq." You cannot solder the metal to the wood. No metallic or other connection whatever is suggested between the groove and the waste-pipe or overflowopcning. N or are washers, or any other equivalent device, suggested as proper to be inserted between the tub and additional foot-board. It is impossible to securel y guard a gain st the shrinking of this board, which will render leakage inevitable, as the only connection contemplated are the screws, rivets, or nails by which itmay be attached to the. tub.

My arrangement is certainly far superior to the one alluded to. It is cheap, secure, ornamental, can be attached, to any tub now in use, and above all, is so constructed that is impossible to become disarrangcd, or get out of order.

Having thus stated the advantages of my invention, and the points wherein it is considered superior to all other methods now in use, I will now subjoin a short and detailed description of its several features, which will readily enable any one skilled inthe art to which it appertains, to make and use the same.

A is an ordinary batlctub, having a metallic lining, A.

On the lower portion oft lo tub and around the ordinary opening, tln'ough which is carried ofl t-hc waste water, is a circular metallic flange, a. This flange is provided with a fiunale-screw thread, a.

C is a brass screw-plug, and is provided atlits ends and on its outer surface with screw-threads c c.

The screw-thread c li'ts in the female-screw thread a of the flange a, and forms a tight joint.

The screw-thread 0 receives 'and forms a tight joint with the ordinary screw-coupling (I.

This coupling d is provided with a circular inner lip or flange, d, which forms a seat for a flange or lip on In the side of the connecting-pipe 0 there is an opening, 0', around which fits and is firmly solderedthe curved end I) of the pipe B.

. The upper curved end b of this pipe B fits tightly around and is firmly soldered, or otherwise attached,

to the overflow-opening l) in the upper section of the foot-board of the tub A. I l

B is a metallic pipe, straight along it. main section and provided with curved or elbow ends b 11 While this arrangement allows the pipe, thr0ughout, almost its entire length, to run nearly parallel with the foot of the tub and in close proximity thereto, thus occupying but little space or room, at the same time, it affords the means whereby a neat, tight, and secure attachment is furnished with the plug 0 and the overflow-opening b.

In the drawing, the several 'features are distinctly shown, and their generalarrangement fully illustrated.

Having thus fully described my invention,

What I-clahn therein as new, and desire to secure by Letters Patent of the United States, is-

The tub A, having a female-screw flange, a, screw connecting-pipe 0, when the same is provided with screw-threads c c and opening 0', and the pipe B, with its curved or elbow ends I) b", when the same are so combined and arranged as to operate substantially as herein described, as and for the purpose specified.

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
